Question

A car starts from rest and uniformly accelerated to a speed of 40 km/h in 5 s . The car moves south the entire time. Which option correctly lists a vector quantity from the scenario?

Answer 1

Explanation:

Speed= distance / time

Making distance the subject of the formula.

Distance = speed × time

Convert km/hr to m/ s

(40× 1000)/3600= 11.1m/s

Distance = 11.1m/s × 5s

Distance= 55.6m

So it is vector ,although the question is not complete.

Answer 2

Answer:

speed: 40 km/h

distance: 40 km

acceleration 8 km/h/s south

velocity: 5 km/h north
